3. As you tighten the crank arm puller on the shaft, the crank arm will pull off the crank arm
shaft. Remove the crank arm from the frame.
III. Inspect the Bottom Bracket Assembly for Looseness.
1. Loosen the lock ring on the left side of the bike using a
lock ring removal tool.
2. Ensure that the right bearing cup is tight. If necessary,
tighten with the bottom bracket tool. Note: the right
bearing cup is reverse threaded!
3. Check the left bearing cup. If the bearing cup is loose,
tighten with your fingers. Use the bottom bracket tool to
tighten the bearing cup – rotate the bottom bracket tool an
additional 10 degrees clockwise.
4. Verify that the bottom bracket spindle is not loose by
tugging on the spindle shaft.
5. Use the lock ring removal tool to tighten the lock ring.
Note: Prevent the left bearing cup from spinning by
stabilizing it with the bottom bracket removal tool.
IV. Reassemble the bike.
1. Apply a thin coat of grease on the left bottom bracket shaft and install the left crank arm on
the bottom bracket shaft. Note: use a rubber mallet to tap the arm onto the bottom bracket
spindle.
2. Apply 1-2 drops of Locktite® 242 on the left crank arm bolt threads. Install the crank arm
bolt and tighten to secure the crank arm. Rotate the pedals a few revolutions and then tighten
the crank arm bolt again to ensure that the crank arm is tightened to 29.5 foot/lbs.
3. Apply a thin coat of grease on the right bottom bracket shaft and install the right crank arm
on the bottom bracket shaft. Align the right crank arm 180° from the left crank arm and push
the crank arm on to the crank arm shaft.
4. Apply 1-2 drops of Locktite 242 on the right crank arm bolt threads. Install the crank arm bolt
and tighten to secure the crank arm. Rotate the pedals a few revolutions and then tighten the
crank arm bolt again to ensure that the crank arm is tightened to 29.5 foot/lbs.
5. Install the belt. Test the belt tension by standing on the pedals with the pedals horizontal to
the floor. Pedal quickly and see if the belt slips. A minimum of slipping is okay, it is impor-
tant not to overtighten the belt.
Note: If you have difficulty keeping the idler pulley aligned remove the tension adjustment screw
and idler pulley from the frame. Slide the idler pulley mounting screw all the way up in the frame.
Install the belt and reinstall the idler pulley nut. Tighten the tension adjustment screw. Tighten
the idler pulley nut. The idler pulley should be aligned with the belt.
6. Reinstall the right side cover.
Note: Inspect the pedal crank arm bolts again after 30 hours (approx. one week).
If loose, remove the bolts; apply Loctite 242 and reinstall. Tighten the bolts to 29.5 foot/lbs.
